The Tesla Roadster is likely the hottest looking vehicle in the company’s repertoire. The new version is also one of the most efficient electric cars we have ever seen. The company took everything they learnt from the Model S and applied it to the Roadster.

With improved battery, aerodynamics and rolling resistance, they are able to extend battery life by 40%-50%! This means the Roadster 3.0 can take you as far as 400 miles on a single charge. Quite impressive, and Tesla is promising a demonstration coming 2015, when they will drive the car from San Francisco to Los Angeles.

Opinion: Electric cars are not suited for today’s driving world. While more charging spots are coming, these are still rare and it’s worrisome to think you can run out of juice in some desert highway, with no charger to be found nearby.

Nokia has finally announced a Chinese launch date for its N1 tablet. The device is said to come to China on January 7th, so we can step following rumors and speculations once and for all.

The Nokia N1 sports a very good set of specs. It carries a 7.9-inch 2048x1536p display, Android 5.0, a 2.3 GHz quad-core Intel Atom processor, 2 GB of RAM, 32 GB of internal storage and 8MP/5MP cameras. It’s expected to cost about $250, which is also quite an attractive price point.

Opinion: Nokia needs to keep in mind that it will be competing in a very harsh market. We have Xiaomi ruling China with the amazing Mi Pad, for example. Does Nokia have what it takes to take on such a big competitor?

We have been expecting the launch of Samsung’s first Tizen-powered smartphone for a long time, and that day is said to be nearing. With that in mind, we are starting to see more clues of the Samsung Z1, with today’s leaked images showcasing it in all its glory.

These are the clearest Samsung Z1 images around. The device also says “DUOS” on the top-right corner, so we can assume it will come with dual-SIM capabilities. Pretty neat, right?

Opinion: This is not the most attractive device, but its rumored $90 price point may just change your mind about it. That is one hell of a price! Another mystery is whether Tizen can take off in a world ruled by iOS and Android. Even Windows Phone is having a hard time.
